FRANCIS J. AREND, OF NEIV YORK` N. Y., ASSIGNOR TO THE DE LAVALSEPARATOR COMPANY, A CORPORATION OF NEW JERSEY.

CENTRIFUGAL CREANIER.

SPECIFICATION forming part of Letters Patent No. 775,487, dated November22, 1904.

Application filed June'23, 1903. SerialNo. 162,714. (No model.)

T0 all whom. it may concern:

Be it known that I, FRANCIS J. AREND, a citizen of the United States,residing at New York city, county of New York, and State of New York,have invented anew and useful Imbowl a liner or division contrivanceconsist-' ing of a series of superposed conical division plates ordisks, the said plates or disks extending from near the periphery of thebowl toward the axis thereof, an oriiiced inlet and distributing deviceextending vertically through and intersecting said plates and openinginto the neutral Zone of the creamer between adjacent plates of thedivision contrivance or liner, the purpose of such combination being'that the full milk will be fed between the disks beyond the cream-walland also by means of the distributing device will be fed inapproximately like quantities to the space between each pair of disks orplates. Without doubt the principle and combination of this patentenable like quantities to be fed into the spaces between each pair ofdisks, and to a substantial, material, and benelicial extent it is socarried out in the specific embodiments of the invention or speciiicmachines disclosed in that patent.

My invention has for its object certain improvements in details ofconstruction which, while not departing from the principle or inventionof that patent, have in practice given a more perfect distribution ofthe full milk into the spaces between the disks or plates. Speakingspecifically, in the Patent No. 640,358 the distributing device is shownin one embodiment of the invention as a tube ortubes slotted from end toend. In another embodiment it is shown as a wing or wings slotted orslit from end to end. I have discovered that if with such machinesinstead of forming the slot in the tube or tubes, wing or wings of thesame width from bottom to top I make the width of the slot of varyingwid th, 5 5 the least width being at the bottom'and the greatest widthat the top, the intermediate slot preferably gradually increasing inwidth, there will be more even distribution of the full milk in all thespaces between the disks. I can also accomplish this result by formingin place of the continuous slot a series of apertures or oriiices, oneopposite each of the openings between the disks.

I will now describe my invention as em- 'bodied in the accompanyingdrawings, in

which- Figure 1 is a vertical section through the bowl of a centrifugalseparator embodying my invention. Fig 2 is a cross-section on 70 theline 2 2, Fig. l. Fig. 3 is a sectional View on line 3 3, Fig. l. Fig. 4is a view similar to Fig. l of a modified form. Fig. 5 is a section onthe line 5 5, Fig. 4. Fig. 6 is a section of a portion of the machine,showing a modi- 7 5 fied form of the orificed inlet anddistributingtube.

A is the bowl; B, the cover; C, the milkoutlet tube; D, the cream-outlettube; E, the frusto-conical disks or plates; F, the central 8ofeed-tube. So far this is descriptive of all the drawings and themachine of Patent N o. 640,358.

Speaking now of Figs. l, 2, and 3, Cr are the distributing-tubes, havingthe slot g. As may 8 5 be clearly seen, Fig. 3, this slot g is of leastwidth at the bottom and gradually increases in width to the top. InFigs. 4. and 5 I use Wings H, similar to the wings of Patent No.640,358. The slot or slit /t in these wings, as 9o may be clearly seenin Fig. 4, is, however, made like the slot of Figs. l, 2, and 3, withthe least width at the bottom and with gradually-increasing width. InFig. 6 the openings J-J-10 in the wings J are formed of a 95 pluralityof oriiices or openings, one in line with each of the spaces between theplates or l disks, the opening J being the smallest and the opening J 10the largest and the intermediate openings gradually increasing in size.This mod iiication, as shown, is adapted to be used with a bowl havingtwelve disks, although of course the number of disks and holes isimmaterial. Of course I do not intend to limit myself to the applicationof the orifices J -J 10 to a wing alone, as they can be applied in placeof a Continuous slot in the tube construction of Figs. 1 to 3; nor do Iintend to limit myself to the position as shown of the slot or openingsin the tubes or wings nor to the number of wings or tubes as shown.

Having now fully described my invention, p what I claim, and desire toprotect by Letters Patent, is-

1. In a centrifugal Creamer, the combination with a divisioncontrivance, consisting of a series of superposed conicaldivision-plates, the plates extending' from near the periphery of thebowl and extending through the separating-space of the bowl, of anoriiiced inlet and distributing device extending vertically through andintersecting said plates, the oritice of said device at the bottomthereof being of lesser size than at the top of said device.

2. In a centrifugal cre-amer, the combination with a divisioncontrivance, consisting of a series of superposed conicaldivision-plates, the plates extending from near the periphery of thebowl and extending through the separating-space of the bowl, of anorificed inlet and distributing device extending vvertically through andintersecting said plates, the orifice of said device at the bottomthereof being of lesser size at the bottom of the device, and

gradually increasing in size between the bottom and the top of saiddevice.

8. In a centrifugal Creamer, the combination,

with a division contrivance, consisting of a series of superposedconical divlsion-plates, the plates extendlng from near the periphery ofthe bowl and extending through the sepaseries of superposed conicaldivision-plates, the plates extending from near the periphery of thebowl and extending through the separating-space of the bowl, of an inletand distributing device provided with orifices'in line with the spacebetween each pair of plates, the size of the orifices graduallyincreasing from the lower end to the upper end lof said device.

5. The combination with a centrifugal-separator drum and a liner thereinof an inletpipe the openings of which are narrower at the lower end thanat the upper end of the said inlet-pipe, substantially as and for thepurpose set forth.

In testimony of which invention I have hereunto set my hand, at New Yorkcity, this 13th day of June, 1903.
